Re: 4.6 Northstar
I am assuming you are referring to the Supercharged N*?
Currently there are 4 N* power plants, LD8 fwd 4.6L~275HP, L37fwd~300HP, LH2 rear wheel dr~305HP, and the LC3 Supercharged.
If you would like additional info on the supercharged N*, then go the the tech section, AJ posted a Tech link article that good info on the gm superchargers.
Naturally Aspirated, compression ratio~10.5:1, 300 HP, 4.6L displacement, 93mm bore x 84mm stroke.
Supercharged, compression ratio ~9.0:1, 4.4L displacement, 91mm bore x 84mm stroke,~ 445 HP.
Is the above at the rear wheels?, I'm not sure, I'll post again when I find out.
